PROBLEM TO BE SOLVED: To provide a method which performs compensation of NC data which can satisfy dynamic characteristics. SOLUTION: In the method, the grinding part of a workpiece is generation-ground by NC data made, based on finishing size at each phase angle from a reference line of the grinding part of the structure, each measurement size at each phase angle from the reference line of the grinding part is measured, each finishing size and measurement size at each phase angle are transformed through Fourier transform, each amplitude ratio of each frequency component of Fourier series of each finishing size to Fourier series of each measurement size is calculated, each amplitude ratio is multiplied by the amplitude of each of the frequency components of Fourier series of the fishing size, the difference between the phase of each frequency component of Fourier series of the measurement size and the phase of each frequency component of Fourier series of the finishing size is taken, the Fourier series of a compensation size is obtained by subtracting each of the differences from the phase of each frequency component of Fourier series of the finishing size, the correction size at each phase angle is obtained through its inverse Fourier transform, and correction NC data are made based on the correction size.
